With Google’s debut, the most important AI agent feature is now the most boring one

Google launched Managed Agents for the Gemini API and recast Antigravity as a platform for building autonomous agent teams.

The setup uses simple Markdown config files instead of custom orchestration code, making agent workflows easier to define and reuse.

The article says Google’s move follows similar managed-agent launches from Anthropic and AWS, showing the runtime pattern has converged across vendors.

AGENTS.md and SKILL.md are emerging as portable configuration standards, pointing to a more interoperable agent ecosystem.

The real competition is shifting from whether managed agent runtimes exist to issues like cost, data control, portability, and lock-in.
